Glass block installation
 
I just noticed that who ever put the glass blocks in our basement window placed the vent square right next to a deck joist. I need to move the vent square down one row and put the glass one up.

Do i chisel them out? How do I install a new one.

Thanks

Take some pictures and some one will get you on the right track.

You will have to get a concrete blade installed on a grinder and cut the mortar out from around the block first, inside and out. If you where to just break the block to remove it you will mostly break the one next to it. depending on how many block high your are there is also the possibility of reinforcement wire mudded into some horizontal coures. so be careful.

Am I going to be able to save the blocks I cut out? I don't have a grinder, but what about a dremel with the right bit?

Personaly, I don't like the Dremel tool for much. I'd probably use a 4" grinder with a diamond wheel. (you can get a really cheapo one from China that can easily do the job)

dudes, I know, but being that the Olympics are in China maybe we could give them a break (no more than 2 weeks)

you will only be able to cut the width of the blade. which is only 1". The glass block are anywhere from 3-3/8" to 3-3/4" thick. the grinder would work much more efficient. you will have to cut both sides.
And plan on breaking a block. It most definitely can be done with out breaking one but the odds are against you as per never doing this before. If one breaks you can get a replacement for around $8.00 A block.
